The register is directly mapped into the processor's address space.

The register address is:

LUT base address + 0x4_0210

PEX1 LUT base address: 348_0000h
PEX2 LUT base address: 358_0000h
PEX3 LUT base address: 368_0000h

(refer to the QorIQ LS1046A Reference Manual, 25.5.1.1 PEX_LUT Memory map).

Also, consider that the register is big-endian (byte swapping is required)
